Analog Devices EE-139 Interfacing ADSP-2191 to AD7476 via SPI Port
This document provides technical guidance on establishing a Serial Peripheral Interface (SPI) connection between the Analog Devices ADSP-2191 digital signal processor and the AD7476 analog-to-digital converter. It details the hardware configuration, including pin connections and voltage level considerations for interfacing the two devices.
The guide also covers the software implementation required to control the SPI port on the ADSP-2191. It explains how to configure system registers, set interrupt priorities, and write assembly or C code to manage data transfers between the master DSP and the slave ADC.
